Create a new Alphabet from a string of symbols of your choice

Standard NanoID generator function

λ: g <- createSystemRandom
λ: nanoID g
x2f8yFadIm-Vp14ByJ8R3

Arguments

:: Alphabet	An `Alphabet` of your choice
-> Length	A `NanoID` length (the standard length is 21 chars)
-> GenIO	The pseudo-random number generator state
-> IO NanoID

Customable NanoID generator function

The default Alphabet, made of URL-friendly symbols.
